You need to add

  $event_box->set_events([qw/pointer-motion-mask/]);

to enable firing the event for every pixel your mouse moves.  If that's
too much, look into using pointer-motion-hint-mask[1].

You need to explicitly enable d'n'd by using the various
Gtk2::Widget::drag_* methods.  If you use a new-ish gtk+,
Gtk2::Widget::drag_source_add_image_targets and
Gtk2::Widget::drag_dest_add_image_targets will probably be helpful.
